Free will is commonly taken to be the ability to make decisions that are free of coercion. But if it was that simple we would not have centuries of debate over the issue. The problem with free will as a term lies in the nature of decision making, which is not done by the conscious mind, inputs being acquired milliseconds prior to consciousness, processing performed milliseconds prior to consciousness, correlation with memory enabling recognition, etc, etc, prior to conscious experience of making a conscious decision.
Thought being brought to consciousness by an underlying process of cognition, a process that has nothing whatsoever to do with will, be it conscious or unconscious.
Alter your brain chemistry and you see the world differently and think and feel in ways you would not normally experience.
The term 'free will' may feel good to say or use, but it is woefully inadequate in representing the cognitive process of decision making.
